∙ 13y ago
- At the positive anode, attrackting negative ions: Two electrons are picked up there from two chlorine ions:
2 Cl- --> Cl2(gas) + 2e-
- At the negative anode, attrackting positive ions: Two electrons are donated to two sodium ions:
2e- + 2Na+ --> 2 Na(solid)

How can cadmium be obtained in its pure form?
By electrolysis of a solution or molten salt containing cadmium ions. Under properly controlled conditions, this will result in deposition of pure cadmium at the cathode.
Can mercury be used as electrolyte?
No, electrolytes are those substances which produce ions in solution or in molten form, Mercury is a pure liquid metal and conduct the electricity.
Is partially molten iron a pure substance or a mixture?
Molten Iron is not a mixture because it is still iron. Melting is a physical change meaning that the chemical makeup of the iron is not changed. Its still the element iron.
How many moles of nacl in 60 grm weight of salt?
The formula mass of NaCl is 23.0 + 35.5 = 58.5Amount of NaCl = 60/58.5 = 1.03mol So there is 1.03 moles of NaCl in a 60 gram pure sample.
What is the pure form of diamond?
Diamond is the pure form of diamond.
Is there a use for a liquid state of pure NaCL?
Electrolysis of molten Sodium chloride(liquid NaCl), can be used to produce Sodium metal and Chlorine
How do scientists separate the sodium out of sodium chloride?
When a mixture of 42% NaCl and 58% CaCl2 is electrolysed in Down'cell pure molten sodium metal is obtained.
Why is molten NaCl rather than solid NaCl used as electrolyte?
The scope is to obtain pure sodium and chlorine.
Are HCl aq NaCl aq HCl g and NaCl s substances?
If you mean pure substances then:HCl(aq) and NaCl(aq) are not pure substances but solutions. The (aq) means the substance is dissolved in water.HCl(g) and NaCl(s) is are pure substances
Which will have the lowest boiling point pure water 0.5 M NaCl aq 1.0 M NaCl aq or 2.0 M NaCl aq?
Pure Water
Is NaCl conductive?
Not as a solid, but dissolve it in water and the ions help electricity conduct through the saltwater. Totally pure water will hardly conduct electricity. The impurities in the water are what allows current to flow.
How can cadmium be obtained in its pure form?
By electrolysis of a solution or molten salt containing cadmium ions. Under properly controlled conditions, this will result in deposition of pure cadmium at the cathode.
Why NaCl turns colourless when melted?
NaCl pure is also colorless at room temperature.
Is salt mixture or pure substance?
pure substance...since it is NaCl...a compound..
Why is there difference in conductivity between 5 percent NaCl solution and pure NaCl?
Pure solide NaCl is not electrically conductive. The water solution of NaCl is an electrolyte and is conductive.
How many grams of nacl would you use to make 100ml of 0.9 percent nacl?
The answer is 0,9 g pure, dried NaCl.
Is sodium chloride a mixture substance?
Sodium chloride, NaCl, is a compound, which is a pure substance. It is a compound because sodium ions and chloride ions chemically bond to each other to form the ionic compound NaCl.
